Book Description
My involvement in the use of natural rubber as a method for the protec 1976. At that time, tion of buildings against earthquake attack began in I was working on the development of energy-dissipating devices for the same purpose and had developed and tested a device that was even tually used in a stepping-bridge structure, this being a form of partial isolation. It became clear to me that in order to use these energy devices for the earthquake protection of buildings, it would be best to combine them with an isolation system which would give them the large displace ments needed to develop sufficient hysteresis. At this appropriate point in time, I was approached by Dr. C. J. Derham, then of the Malaysian Rubber Producers' Research Association (MRPRA), who asked if I was interested in looking at the possibility of conducting shaking table tests at the Earthquake Simulator Laboratory to see to what extent natural rubber bearings could be used to protect buildings from earthquakes. Very soon after this meeting, we were able to do such a test using a 20-ton model and hand-made isolators. The eady tests were very promising. Accordingly, a further set of tests was done with a more realistic five storey model weighing 40 tons with bearings that were commercially made. In both of the test series, the isolators were used both alone and with a number of different types of energy-dissipating devices to en hance damping.

Book Description
Base isolation technology offers a cost-effective and reliable strategy for mitigating seismic damage to structures. The effectiveness of this new technology has been demonstrated not only in laboratory research, but also in the actual response of base-isolated buildings during earthquakes. Increasingly, new and existing buildings in earthquake-prone regions throughout the world are making use of this innovative strategy. In this expanded and updated edition, the design methods and guidelines associated with seismic isolation are detailed. The main focus of the book is on isolation systems that use a damped natural rubber. Topics covered include coupled lateral-torsional response, the behavior of multilayer bearings under compression and bending, and the buckling behavior of elastomeric bearings. Also featured is a section covering the recent changes in building code requirements.

Book Description
Complete, practical coverage of the evaluation, analysis, and design and code requirements of seismic isolation systems. Based on the concept of reducing seismic demand rather than increasing the earthquake resistance capacity of structures, seismic isolation is a surprisingly simple approach to earthquake protection. However, proper application of this technology within complex seismic design code requirements is both complicated and difficult. Design of Seismic Isolated Structures provides complete, up-to-date coverage of seismic isolation, complete with a systematic development of concepts in theory and practical application supplemented by numerical examples. This book helps design professionals navigate and understand the ideas and procedures involved in the analysis, design, and development of specifications for seismic isolated structures. It also provides a framework for satisfying code requirements while retaining the favorable cost-effective and damage control aspects of this new technology. An indispensable resource for practicing and aspiring engineers and architects, Design of Seismic Isolated Structures includes: * Isolation system components. * Complete coverage of code provisions for seismic isolation. * Mechanical characteristics and modeling of isolators. * Buckling and stability of elastomeric isolators. * Examples of seismic isolation designs. * Specifications for the design, manufacture, and testing of isolation devices.

Book Description
In 1998 Armenia was commemorating the tenth anniversary of the catastrophic Spitak earthquake. The Second International Conference on "Earthquake Hazard and Seismic Risk Reduction" sponsored by the Government of the Republic of Armenia and United Nation's International Decade for Natural Disaster Reduction (UN/IDNDR) was held in dedication to that event between 14-21 September (later referred to as Yerevan Conference). The Yerevan Conference has been organized by the National Survey for Seismic Protection (NSSP) of the Republic of Armenia. All level's decision-makers (from the ministers to the local authorities), politicians, scientists, leaders of the executive and legislative powers, psychologists, leading businessmen, representatives from the private sector and the media as well as from the International Organizations have been invited by the Armenian NSSP to take part in joint discussion of the Seismic Risk Reduction Problem for the first time in the history of such forums. Armenian NSSP's such initiative has been triggered by the experience of the Spitak earthquake and other disasters. They showed that it will be possible to reduce the risks, posed by the natural disaster, only through the common efforts of all the community in co-operation with the International institutions.

Book Description
Widely used in civil, mechanical and automotive engineering since the early 1980s, multilayer rubber bearings have been used as seismic isolation devices for buildings in highly seismic areas in many countries. Their appeal in these applications comes from their ability to provide a component with high stiffness in one direction with high flexibility in one or more orthogonal directions. This combination of vertical stiffness with horizontal flexibility, achieved by reinforcing the rubber by thin steel shims perpendicular to the vertical load, enables them to be used as seismic and vibration isolators for machinery, buildings and bridges. Mechanics of Rubber Bearings for Seismic and Vibration Isolation collates the most important information on the mechanics of multilayer rubber bearings. It explores a unique and comprehensive combination of relevant topics, covering all prerequisite fundamental theory and providing a number of closed-form solutions to various boundary value problems as well as a comprehensive historical overview on the use of isolation. Many of the results presented in the book are new and are essential for a proper understanding of the behavior of these bearings and for the design and analysis of vibration or seismic isolation systems. The advantages afforded by adopting these natural rubber systems is clearly explained to designers and users of this technology, bringing into focus the design and specification of bearings for buildings, bridges and industrial structures. This comprehensive book: includes state of the art, as yet unpublished research along with all required fundamental concepts; is authored by world-leading experts with over 40 years of combined experience on seismic isolation and the behavior of multilayer rubber bearings; is accompanied by a website at www.wiley.com/go/kelly The concise approach of Mechanics of Rubber Bearings for Seismic and Vibration Isolation forms an invaluable resource for graduate students and researchers/practitioners in structural and mechanical engineering departments, in particular those working in seismic and vibration isolation.

Book Description
This book contains 9 invited keynote and 12 theme lectures presented at the 14th European Conference on Earthquake Engineering (14ECEE) held in Ohrid, Republic of Macedonia, from August 30 to September 3, 2010. The conference was organized by the Macedonian Association for Earthquake Engineering (MAEE), under the auspices of European Association for Earthquake Engineering (EAEE). The book is organized in twenty one state-of-the-art papers written by carefully selected very eminent researchers mainly from Europe but also from USA and Japan. The contributions provide a very comprehensive collection of topics on earthquake engineering, as well as interdisciplinary subjects such as engineering seismology and seismic risk assessment and management. Engineering seismology, geotechnical earthquake engineering, seismic performance of buildings, earthquake resistant engineering structures, new techniques and technologies and managing risk in seismic regions are all among the different topics covered in this book. The book also includes the First Ambraseys Distinguished Award Lecture given by Prof. Theo P. Tassios in the honor of Prof. Nicholas N. Ambraseys. The aim is to present the current state of knowledge and engineering practice, addressing recent and ongoing developments while also projecting innovative ideas for future research and development. It is not always possible to have so many selected manuscripts within the broad spectrum of earthquake engineering thus the book is unique in one sense and may serve as a good reference book for researchers in this field. Audience: This book will be of interest to civil engineers in the fields of geotechnical and structural earthquake engineering; scientists and researchers in the fields of seismology, geology and geophysics. Not only scientists, engineers and students, but also those interested in earthquake hazard assessment and mitigation will find in this book the most recent advances.
